If you multiplied 637 by 912, what would be the units digit of the answer

4

Step-by-step explanation:

The units digit will be 4, because 7*2 = 14, (units digit is 4)

10% of increase is the final answer! : )

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
